Ultra-fast Pulse Generating Modulator Driver | SIMTRUM Photonics Store

Ultra-fast Pulse Generator for TCSPC

Ultra-fast Pulse Generator for TCSPC (100ps, +/- 5V)

STNPG-1H20A is an ultra-fast pulse generator especially for driving M-Z modulator. It has precision pulse width and pulse height control and it  can accept any logic level as trigger input. The pulse width can be set to  lock or tuning mode by pressing the knob, while entering the lock mode,  the last setting will be saved for power-cycling convenience. The pulse  height can also be changed by another knob, while it has additional  coarse tuning mode for faster adjustment.

 

Compared to previous model, STNPG-1H20A integrates a high-performance temperature control system for its RF gain block, therefore the output pulse stability of height and width is greatly improved, that is  resistant to ambient temperature changes and it can run stably for a long  time.

Note:

The maximum pulse width may be limited by the input pulse width.

The maximum pulse amplitude is tested @ 100MHz trigger input and 200ps pulse width.

The power consumption may up to 35 watts within a few seconds while power-on, because the module TEC is achieving the target temperature.

 


Power Supply - Users should use a high quality 12V DC  power supply with at least 3A current rating. Either the  attached AC-power adaptor or a high-quality linear power  supply is recommended.

 

Pulse Width Control – Users may press the knob to toggle  between lock/unlock mode for pulse width control. The pulse width can be adjusted by turning the knob in unlock  mode, while pulse width can be fixed and stored by pressing  the knob into lock mode. Each time power cycling, pre-stored pulse width will be loaded automatically with lock  mode on.

 

Pulse height control – Users may press the knob to toggle  among lock/coarse-tuning/fine-tuning mode for pulse  height control. The last tuned pulse height can be fixed and  stored by pressing the knob back into lock mode. Each time  power cycling, pre-stored pulse height will be loaded  automatically.

 

Trigger threshold adjustment - The threshold is pre-set to  0V by factory default. The LED of TRIG‘D is steady off when  trigger is not present or not properly triggered. Adjusting the trigger threshold with a screw driver till the LED turns  blinking, if needed.

 

LED indicators

 

Temp. Control Debug Port – for factory use only.

 

USB Communication Port – Users can set the pulse width and height by connecting this  port to a computer via a USB type-B cable. The protocol is based on a series of simple  four-byte UART commands as follows
